Ok guys, i'm a 17 year old athlete, roughly 6'1 ~170
I'm in the off season right now in terms of tennis, and give me some workouts so i'll maintain and be in even better shape this summer for primarily tennis.

I lift weights and do sprints, but don't have a regimented workout so any suggestions would be great

try suicides, they work VERY well, and try to beat your previous time each errr.....time, lol.

I saw the video for the agility ladder and have to admit they look very tough to do, and looks kinda fun. You could make your own agility ladder with some nylon rope and some wooden dowels, drill holes in at the end and then thread the rope through, and voila.
